Hey ! I just installed the 2.8 Firmware and the Kemper had huge problems with the update: - When starting the Kemper it takes around 10 minutes until the Kemper starts. - After starting and loading my rigs the kemper hangs up - I inserted USB stick while the Kemper was on and it was not recognized - After that I took an empty USB with 2.7 Firmware on it and restarted the Kemper while holding the < and > buttons. - The Kemper started to boot from the USB stick but than an error warning appears, saying: "ERROR: Firmware update doesn´t support this hardware". I tried this with different USB sticks and different Firmware updates (2.7 - 2.6) - I also tried to reset the system settings, but it didn´t change anything - I also erased the internal flash memory, so my Kemper has got no rigs or anything on it. After that I tried to boot from my USB Sticks (one with 2.7 and one with 2.6) but nothing changes and I always get the error warning. Please help me ;(
